This adds bundle-specific behaviour into the register allocator. I think this is wrong!

>From an RAs perspective the bundle really should be the union of all operands on a single instruction. So the real question to solve here is what to do with an instruction that has "%vreg0<imp-def,dead>" and "%vreg0<def>" at the same time and not checking for bundles and changing behaviour when we have them.
